Hi CCL - we got your PM and are ready to help!
Without knowing Ockey's temperment or disposition, I will say off the bat that if he is normally a calm, friendly cat, he will not stay confined to a cage or a few rooms for long. He will use the cage as a safe place when scared, but he will explore. Obviously, your idea of keeping him confined to one area of the house is good at first, but don't be surprised when you find him wanting to explore more. We just allowed Pips to take it at his own pace, and at that time, we were both gone most of the day.

But they figure things out fast! For example, when I brought Pips home, I immediately got the flu and Jim had to take over the intro duties with a blind 5 month old kitten. He didn't know any better and just took the kid everywhere in the house and let him sniff around. Combined with TigerTiger being big brother, Pippin was tooling around the upstairs within a week! My point is not to assume that Ockey will only want to stay in his cage. When he becomes comfortable, he will want to be with you or the other cats that seem friendly. Hopefully, some of your tribe will be interested in making friends, but they will be wary of him at first, having never seen a cat that bumps into things.

He will memorize the house layout very quickly - via rugs on the floor, changes in flooring texture, corners of rooms and hallways, how sound bounces off the walls, what sounds come from what areas of the house (Pips can hear the fridge door a mile away!). I'm convinced that cats rely much more on their whiskers and ears than their eyes when sensing things and I have read that they don't see well close up anyway. That said, try to keep things consistent for him at first - no major renovations or furniture moving! Cat boxes in the same place always. And we put a rug in front of the catbox so Pips knew he was getting close!

And this goes without saying, I'm sure (although I goofed a couple of times at the toy store...) buy toys that rattle, squeak or otherwise make a little noise. Ockey can't see what he can't hear!
Pips just got himself a track ball toy and loves the sound of the ball going round and round - very intriguing at 3 AM.

Couple of other tricks...we built a little ramp to attach to the cat tree for getting up an down without crashing. And, we stacked storage bins with soft blankets around the beds so he could get up and down via the stair step method. Eventually though, Pips learned how far the jump from the bed to the floor was and didn't need this "baby stuff" anymore! Basically though, whatever they can jump up to...give them a way to get down safely by not jumping.

And finally, when blind cats get scared, they get low and backup usually against a wall, corner or piece of furniture. They backup, because they want to keep their hearing oriented in front of them, so if he does get scared, stop your movement, let him get himself oriented first before you start walking toward him to pick him up, otherwise he will panic. Pips rarely gets freaked, but when he does, I kneel down to talk to him, so I don't seem so big. Remember they are going to judge size by where the sound comes from...

Hey, if you take this guy home, you are going to figure things out, I'm sure, but the most important thing is that they just want to be loved. They adapt to the physical stuff very well once they know they are loved and wanted in this world!

Good luck and don't hesitate to ask Pippin, William and TigerTiger for any other tips!
